The Scary Way Skipping a Bang Trim Can Hurt You

Over the past couple of years, I've noticed that a strange thing happens if I go a week or two past the due date of my bang trim. For the record, I have thick hair and blunt, full bangs (that's them, above). When they grow a little too long, the skin from my eyelids to my eyebrows starts to freak out. It's angry, red, irritated—and painful. Does this happen to anyone else? I wanted answers, so I asked Joshua Zeichner, the director of cosmetic and clinical research at Mount Sinai Hospital in New York City, what was going on.
